Behold, Dan Graves signalled from keyed 4-1000A filament:

Is this "Sound Recorder" a Windows program or Linux?

Sound Recorder is part of the Windows install.

Can MP3 players play .ogg Vorbis files? What Windows software will play
those (and maybe even convert them to MP3 or WAV)?

Most all computer players, like Winamp, will play Vorbis files.
www.vorbis.com gives a list of goodies for you.

For converting, try the freeware program CDex - it's fabulous!
